Notes:
Two relatively simple schemes are described for the interactions of grain deformationsduring large plastic deformations with the aim of evaluating their influence on texture development.The stress transfer model basically assumes that there is some degree of stress transfer across theboundaries proportional to the boundary area. The reduced stress incompatibility model minimizesthe stress incompatibilities between each grain and their surrounding grains These models assume3D topological schemes using evolving truncated octahedra for the spatial distributions of thegrains. They are applied to the cases of hot rolled and cross forged Al alloys. Both give quite similarpredictions for texture development which are moderate improvements on the Taylor models,confirming that the incorporation of grain interaction effects can be useful for texture modelingwithout major modifications. Moreover, they can yield interesting results for local orientationeffects and their influence on orientation stability; an example of cube grains hot rolled in differentcrystallographic surroundings is also treated
